Motion data based processing time window for positioning signals

Abstract

An object position is estimated on the basis of at least one positioning signal (PBS) from a transmitter on an object ( 30 ). Motion data from a sensor on the object ( 30 ) are used as a basis for determining a processing time window. Processing of the at least one positioning signal (PBS) and/or positioning data (PD) derived from the at least one positioning signal is accomplished based on the determined processing time window. The transmitter and the sensor may be integrated in a tag device ( 10 ) attached to the object ( 30 ).
